What is the pressure that is exerted by a box tjat has a dimension of 12cm long and 14cm wide and has a force of gravity on the box of 40N?

To find the pressure exerted by the box, we need to divide the force by the area on which the force is acting. In this case, the force of gravity is acting on the surface area of the box.

Step 1: Calculate the area of the surface that is in contact with the force. Since the box has a length of 12 cm and a width of 14 cm, the area can be calculated by multiplying these two dimensions: Area = Length × Width.

Area = 12 cm × 14 cm = 168 square cm.

Step 2: Convert the area to square meters, as the SI unit of pressure is pascal (Pa) and it is measured in square meters. To convert square centimeters to square meters, divide by 10,000 (since there are 10,000 square centimeters in a square meter):

Area = 168 square cm ÷ 10,000 = 0.0168 square meters.

Step 3: Calculate the pressure by dividing the force by the area:

Pressure = Force ÷ Area.

Pressure = 40 N ÷ 0.0168 square meters.

Using a calculator, the pressure exerted by the box is approximately 2380.95 Pa (rounding to 2 decimal places).

Therefore, the pressure exerted by the box is approximately 2380.95 Pa.
